A system designed to enhance the power output of the Nissan 370Z by forcing more air into the engine’s combustion chambers. In this configuration, the forced induction component is situated towards the rear of the vehicle, differing from traditional engine bay installations. This setup necessitates specific plumbing and intercooling solutions to effectively deliver the compressed air to the engine.
The adoption of a remotely mounted forced induction system can offer benefits such as improved engine bay cooling and potentially simplified installation in certain vehicle models. Historically, this approach has been utilized to overcome space constraints within the engine compartment or to achieve specific performance characteristics. The effectiveness of such a system is predicated upon factors including turbocharger sizing, intercooler efficiency, and the quality of the exhaust and intake piping.
The following sections will delve into the specific components, installation considerations, performance implications, and potential drawbacks associated with this particular power enhancement approach for the Nissan 370Z platform.
1. Heat Management
The rearward placement of a turbocharger introduces significant thermal considerations. Unlike traditional engine bay setups where airflow aids in heat dissipation, a remotely mounted unit is often situated in a more confined space, closer to the differential and other temperature-sensitive components. The exhaust gas, which spins the turbine, exits at extremely high temperatures. Without adequate shielding and ventilation, this radiant heat can negatively impact surrounding components, leading to premature wear or failure. For example, overheating the differential oil can reduce its lubricating properties, accelerating wear on the gears and bearings within the differential.
Mitigating these thermal risks requires meticulous planning and execution. Heat shields, often constructed from materials like aluminum or ceramic composites, are essential for deflecting radiant heat away from vulnerable components. Wrapping the exhaust piping with thermal insulating materials can further reduce heat soak. Some installations incorporate dedicated cooling systems, utilizing fans or oil coolers to maintain optimal operating temperatures. The effectiveness of these measures directly impacts the longevity and reliability of both the forced induction system and the vehicle’s drivetrain.
Effective heat management is not merely an ancillary consideration; it is an integral element of a successful rear-mounted forced induction installation. Neglecting this aspect can lead to diminished performance, increased maintenance, and potentially catastrophic failures. Therefore, proper heat shielding, insulation, and cooling strategies are paramount when contemplating this type of power enhancement on a 370Z, ensuring the modification enhances performance without compromising reliability.
2. Boost Response
The pursuit of enhanced power through forced induction often encounters the critical factor of boost response. With a rear-mounted turbocharger on a 370Z, the inherent distance introduces unique challenges in achieving rapid and predictable power delivery. This is the story of minimizing that delay.
-
Piping Length and Volume
The extended length of the intake piping, a defining characteristic of remote turbocharger installations, creates a larger volume that must be pressurized before reaching the engine. This volume acts as a reservoir that needs to be filled by the turbocharger. Consequently, the time required for the engine to feel the effects of the forced induction increases, resulting in turbo lag. Imagine a long garden hose; the further the water has to travel, the longer it takes to feel the pressure change at the nozzle. Similarly, the lengthy piping demands more time to build pressure, affecting responsiveness.
-
Turbocharger Size Selection
Choosing the correct turbocharger size is paramount to mitigating lag. A larger turbocharger, while capable of producing higher peak power, typically requires more exhaust gas energy to spool up, exacerbating the response delay. Conversely, a smaller turbocharger will spool up more quickly but may lack the capacity to deliver the desired airflow at higher engine speeds. Striking a balance between these two characteristics is essential for optimizing boost response. The tale of Goldilocks applies here; one seeks the turbocharger that is neither too large nor too small, but just right for the engine’s operating range.
-
Intercooler Design and Placement
The intercooler, responsible for cooling the compressed air, also plays a role in boost response. Larger intercoolers, while offering superior cooling capabilities, introduce additional volume into the intake tract. This added volume can further contribute to lag. Placement of the intercooler, often dictated by the rear-mounted turbocharger configuration, can influence the length of the piping and thus, the overall responsiveness. Imagine the intercooler as a filter; while it cleans the air, its size and location affect how quickly air can pass through.
-
Electronic Boost Control
Employing electronic boost control systems can improve boost response by precisely managing the turbocharger’s wastegate. These systems allow for finer control over boost pressure, optimizing the turbocharger’s operation across the engine’s RPM range. Electronic boost controllers can compensate for the inherent lag associated with rear-mounted turbochargers by strategically adjusting boost levels. This technology acts as a conductor of an orchestra, ensuring each instrument plays in harmony for optimal performance.
Ultimately, achieving satisfactory boost response with a rear-mounted forced induction system requires a holistic approach. Careful consideration of piping length, turbocharger sizing, intercooler design, and electronic boost control is critical to minimizing lag and maximizing the benefits of forced induction on a 370Z. The story of improving boost response is one of careful engineering and precise calibration.
3. Piping Length
The tale of the rear-mounted turbocharger on a 370Z is, in no small part, the story of its piping. The distance between the engine’s exhaust manifold and the remotely located turbocharger dictates the length of the exhaust piping, while the journey from the turbocharger’s outlet to the engine’s intake plenum defines the length of the intake piping. These pathways, far longer than those found in conventional turbocharger setups, significantly influence the system’s performance and responsiveness. The longer the pathways, the higher possibility of failure on the 370z rear turbo kit.
-
Volume and Inertia
Imagine the piping as a wind instrument. The longer the instrument, the more air it takes to produce a sound. Similarly, lengthy piping increases the volume of air that must be pressurized before the engine experiences the benefits of forced induction. The air itself has mass, and this inertia resists changes in flow. The turbocharger must first overcome this resistance before boosting pressure, resulting in noticeable lag. Consider, as an example, a high-altitude mountain climber. Each breath requires more effort to draw air into the lungs, mimicking the difficulty of filling extended piping.
-
Pressure Drop
Friction, an inescapable force, acts upon the air as it traverses the piping. This friction creates resistance, leading to a pressure drop. Over extended distances, this pressure drop can become significant, diminishing the amount of boost that ultimately reaches the engine. Think of water flowing through a long, narrow pipe; the pressure at the end will be lower than at the beginning due to friction against the pipe’s walls. The longer the pipe, the greater the pressure loss, impacting the overall efficiency of the setup for the 370z rear turbo kit.
-
Heat Loss
As compressed air travels through the intake piping, it is vulnerable to heat loss. This is especially true in areas exposed to ambient temperatures. Cooled air is denser, meaning there’s less oxygen for each intake. This reduces combustion efficiency. For instance, an exposed pipe in a cold climate is less efficient than one that is heated, meaning there’s a reduction in the power generation that could be achieved.
-
Material and Routing
The material of the piping affects heat absorption/dissipation and weight. Steel is strong but heavier. Aluminum is lighter but more prone to damage and absorbs heat easier. The routing can impact airflow and how easily repairs can be done.
These facets collectively paint a picture of the challenges presented by lengthy piping in a rear-mounted turbocharger system. While the remote location offers certain advantages, the increased piping length introduces complexities that must be carefully addressed to ensure optimal performance and responsiveness. The piping becomes a critical pathway, and its design and execution determine whether the potential of the rear turbo kit is fully realized on the 370Z.
4. Weight Distribution

This shift in weight distribution towards the rear impacts several aspects of handling. Increased rear weight can improve traction during acceleration, potentially reducing wheelspin and enhancing straight-line performance. However, it can also lead to a more pronounced oversteer tendency, particularly during cornering. The car may feel more eager to rotate, demanding greater driver skill to manage and control the vehicle’s trajectory.
-
Impact on Suspension Tuning
The altered weight distribution necessitates careful adjustments to the suspension system. Spring rates, damper settings, and sway bar configurations must be optimized to accommodate the new weight bias. Failure to properly tune the suspension can result in compromised handling, leading to unpredictable behavior and reduced driver confidence. For example, a softer rear spring rate may be required to compensate for the increased weight, preventing the rear end from feeling overly stiff or bouncy. Conversely, stiffer sway bars might be needed to counteract the increased oversteer tendency.
-
Trade-offs in Handling Characteristics
The changes in weight distribution introduce a complex set of trade-offs in handling. While increased rear weight can enhance traction, it can also diminish the car’s agility and responsiveness. The 370Z may feel less nimble and less eager to change direction. The polar moment of inertia, a measure of a car’s resistance to rotation, increases with rear-mounted weight, making the car feel more sluggish during transitions. Striking the right balance between traction and agility requires careful consideration of driving style, road conditions, and overall performance goals.
-
Optimizing for Specific Applications
The ideal weight distribution for a 370Z equipped with a rear-mounted turbocharger depends on the intended use of the vehicle. A car primarily used for drag racing might benefit from a more pronounced rearward bias, maximizing traction for straight-line acceleration. However, a car intended for track days or spirited road driving would likely require a more balanced weight distribution to ensure predictable and responsive handling. The final configuration should reflect the driver’s priorities and the demands of the driving environment.
Thus, the decision to install a rear-mounted turbocharger is not merely a question of power enhancement; it represents a significant alteration to the car’s fundamental handling characteristics. The subtle shift in weight distribution necessitates careful consideration and meticulous adjustments to ensure that the added power is delivered effectively and controllably. Ultimately, the success of a rear-mounted forced induction system hinges not only on its ability to generate horsepower, but also on its integration with the car’s inherent dynamics.

However, the unconventional location of the turbocharger introduces unique challenges in determining the optimal intercooler placement. Where it sits dictates how well the system works.
-
Proximity to the Turbocharger
The closer the intercooler is to the turbocharger, the shorter the piping and the quicker the boost response. This is the ideal position for the 370z rear turbo kit. However, this proximity may be difficult to achieve in a rear-mounted configuration due to space limitations. Imagine a relay race where the baton (cooled air) must be passed efficiently. A shorter distance between runners (turbocharger and intercooler) means less time lost. In reality, compromises must often be made, balancing the desire for quick response with the practical constraints of vehicle packaging.
-
Airflow Considerations
An effective intercooler requires a consistent flow of cool air to dissipate heat. This is key with any 370z rear turbo kit. Positioning the intercooler in an area with limited airflow reduces its efficiency, negating the benefits of cooling the compressed air. Front-mounted intercoolers typically receive ample airflow, but rear-mounted setups may struggle in this regard. Think of a wind turbine needing open space to generate power; similarly, an intercooler needs unobstructed airflow to perform its function effectively. Creative solutions, such as ducting or forced-air induction, may be required to ensure adequate airflow to the intercooler.
-
Piping Length and Complexity
Intercooler placement directly influences the length and complexity of the intake piping. Longer piping increases the volume that must be pressurized, contributing to turbo lag. Complex routing introduces additional pressure drop and potential points of failure. This is especially important with a 370z rear turbo kit. Consider the piping as a series of interconnected highways; the shorter and straighter the roads, the faster the journey. Optimizing intercooler placement involves minimizing piping length and simplifying routing to maximize efficiency and minimize lag.
-
Thermal Management
The intercooler itself is a heat source, albeit one that dissipates heat rather than generating it. Placing the intercooler in close proximity to temperature-sensitive components, such as the differential or fuel tank, can create thermal management issues. Shielding and insulation may be required to prevent heat soak and ensure the proper functioning of these components. Think of the intercooler as a radiator; while it removes heat from one system, it also introduces heat into its immediate surroundings.
